<?php
// Perform an action, as an AJAX request.
//
// It is bad design to put actions in GET parameters (because
// reloading the page will execute the action again) or POST
// parameters (because it effectively disables the "back" button).
//
// It also means we must hide such links from search engines,
// which frequently penalize sites that generate different
// content for browsers/robots.
//
// Instead, use an AJAX request, such as
//
// <a href="#" onclick="jQuery.post('action.php',{action='foo',p1='bar'}, function(){location.reload()});">click-me!</a>
// <a href="#" onclick="jQuery.post('action.php',{action='foo',p1='bar'}).success(location.reload()).error(alert('failed'));">click-me!</a>
//
// Most actions will not need separate success() and error().
// Typically this may occur if an action has already been submitted, or
// the login session has expired. In these cases, reloading the page is
// the correct response for both success/error.
